clearlyunderstood by taking the ex-ample shown in Fig. 19. Itwould not be necessary to usefor as small a number of lights as 10, but it will serve toillustrate the point. Allowing 50 volts per lamp, so as toinclude the line drop, we would require 500 volts for oper-ating the single circuit in Fig.… … Fig. 18. a multicircuit arrangement 30 ELECTRIC LIGHTING. 18 are connected directly in series, we have 500 volts acrossthe circuit. In the second case, we have the state of affairs shown inFig. 19 (b). Suppose that we take the point 1 as a startingpoint and assume that it is at zero potential. The…
